Title: Air valve type carburetor

IPC: F02M7/17

Granted: 1980-08-12
Abstract: AIR VALVE TYPE CARBURETOR          Abstract of the Disclosure An air valve type carburetor has a pressure transducer for detecting the pressure in a venturi portion of the carburetor and emitting electric signals corresponding to such pressure.  A passage introduces a vacuum from a suction passage supplying air-fuel mixture to an engine downstream of a throttle valve to a suction chamber containing one end of a slidable piston, the other end of which is disposed in the venturi portion of the suction passage.  An electromagnetic valve is provided as well as a control unit.  The control unit receives electric signals from the pressure transducer, compares these signals with a reference value and emits signals corresponding to the difference.  The electromagnetic valve controls the vacuum transmitted to the suction chamber through the passage according to the difference signals from the control unit, so that the pressure in the venturi portion is kept constant.  The advantage is that the air-fuel ratio is subject to much less fluctuation than in a conventional carburetor when the position of the throttle value is changed suddenly.

Abstract: IMPROVED END FITTING FOR HIGH-VOLTAGE FUSE           ABSTRACT: An improved end fitting for a high-voltage fuse is disclosed.  The fuse is of the general type having a movable striker pin which resides in a first posi-tion as long as a fusible element of the fuse remains intact. Should the fusible element cease to be intact, through fusing thereof or mishandling of the fuse, the striker pin moves to a second position to partially exit beyond an end of the fuse when a sharp end of the striker pin pierces a seal at the fuse end.  The improved end fitting is removably mountable to the fuse and includes a body having a bore therethrough.  The first end of the body surrounds and encloses the seal.  A rod, mounted for movement in the bore at the end of the body, resides in a first normal location when the striker pin is in the first normal position, and in a second location when the striker pin is in the second position.  Facilities which indicate that the rod is in the second location may include a vividly colored portion of the rod which is visible only when the rod is in the second location.  The end fitting is so designed that it prevents the escape from the second end of the body of gas vented from the pierced seal.  The end fitting, however, does permit the escape of such gas from the first body end in such a diffuse manner as to greatly reduce the possibility of flashover between adjacent energized live parts.  The end fitting also limits the movement of the rod and retains it within the bore at the second location.  This has the result of limiting the movement of the striker pin beyond the seal to retain it partially within the bore and partially within the fuse.

Abstract: FLUID DRIVE COUPLING                    Abstract of the Disclosure A fluid drive coupling is provided which includes a platelike first member rotatably mounted within a chamber formed in a second member, the latter also being rotatably mounted.  Both members are rotatable about a common axis and one of the members is driven by an external force. The chamber is formed into an annular fluid drive section having surfaces thereof in close proximity to substantial outer opposite surface portions of the first member whereby rotation of one member imparts rotation to the other member through a fluid disposed within the chamber drive section.  The chamber is also formed into an inner section, a portion of which, disposed to one side of the first member, is separated into first and second fluid reservoirs interconnected to one another only through a port.  A thermal responsive valve $8 mounted on the second member and is rotatable therewith.  The valve effects opening and closing of the port in response to predetermined temperatures.  An elongated cavity is formed in the second member adjacent to and in communication with a peripheral segment of the chamber drive section.  An elongated skimming means is dis-posed in slip fit relation within the cavity and has a portion thereof projecting into the chamber drive section and encom-passing a peripheral portion of the first member.  When the first member is rotating in one direction relative to the second member, the skimming means will cause removal of fluid from the surfaces of the rotating first member encompassed thereby and divert the removed fluid into the cavity whereupon the fluid will flow from the cavity into the first reservoir.

Abstract: OVERSPEED PROTECTION CONTROLLER EMPLOYING      INTERCEPTOR VALVE SPEED CONTROL                 ABSTRACT OF THE DISCLOSURE An overspeed protection controller (OPC) which is incorporated as part of a turbine speed/load control system for the purpose of controlling the monitored speed of a steam turbine at a first predetermined speed valve subsequent to an OPC activation is disclosed.  The governor and inter-ceptor valves of the steam turbine are positioned controlled by a set of electrohydraulically operated valve position servo systems.  The OPC provides for rapid hydraulic closure of each valve when activated by either a detection of an interruption of generated electrical power flow to a power system load when the generated electrical power is greater than a predetermined value or the detection of the monitored turbine speed being greater than a second predetermined speed value.  The rapid closure of the valves results in an interruption of stream flow to the high and lower pressure turbine sections of the turbine system which causes steam energy to be trapped in the reheater which is disposed between the turbine sections.  The OPC is deactivated subsequent a predetermined time interval after the detection of generated power interruption when the monitored turbine speed is no longer greater than the second predetermined speed value.  In response to the deactivation, the OPC controls the rotating speed of the turbine by positioning the interceptor valves to admit steam from the reheater to the lower pressure turbine sections in accordance with a continuous function based on the difference between the monitored turbine speed and the first predetermined speed.     value.  Thus, the trapped stream energy in the reheater is utilized for keeping the turbine at the first predetermined speed value to permit rapid resynchronization of the turbine system with the power system load.
